This document (CEN/TS 15119-2:2012) has been prepared by Technical Committee CEN/TC 38 “Durability of
wood and wood-based products”, the secretariat of which is held by AFNOR.

CEN/TS 15119 is composed of the following parts:
Part 1: Wood held in the storage yard after treatment and wooden commodities exposed in Use Class 3
(not covered, not in contact with the ground) — Laboratory method;
Part 2: Wooden commodities exposed in Use Class 4 or 5 (in contact with the ground, fresh water or sea
water) — Laboratory method.
This document is a revision of Technical Specification published in 2008 in order to consider the OECD 313
which covers the same topic.
Compared to CEN/TS 15119-2:2008 the following modifications have been made:
a) quality criteria for accuracy and reproducibility added in 2.3;
b) provisions for properties of the sea water used for the test added in 2.4.2;
c) procedure for sealing of end grain specified in more detail in 2.7.2;
d) in 2.7.5.2 time intervals for replacement of the water specified and total testing time increased from
19 days to 29 days;
e) reference to extrapolation of results to 1 year or 10 years deleted;
f) recording forms in Annex A modified;
g) Annex B for general recommendations added;
h) Bibliography extended.

Introduction
The emissions from preservative treated wood to the environment need to be quantified to enable an
environmental risk assessment of the treated wood. This document describes a laboratory method for the
estimation of emissions from preservative treated wood in the case where the preservative treated wood is not
covered by a physical protection and is in contact with the ground, fresh water or seawater. There are three
situations in this case where emissions could enter the environment:
a) emissions from treated wood in contact with the ground. Use Class 4A. Emissions from the surface of the
treated wood could enter the soil via the soil water;
b) emissions from treated wood in contact with fresh water. Use Class 4B. Emissions from the surface of the
treated wood could enter the water;
c) emissions from treated wood in contact with sea water. Use Class 5. Emissions from the surface of the
treated wood could enter the sea.
The method is a laboratory procedure for obtaining water samples (leachate) from treated wood in contact
with water, at increasing time intervals (complete duration of 29 days). The quantities of emissions in the
leachate are related to the surface area of the wood and the length of exposure, to estimate a flux in
milligrams per square metre per day.
The quantity of emissions can be used in an environmental risk assessment of the treated wood.
1 Scope
This Technical Specification specifies a laboratory method for obtaining water samples from treated wood
which has been in conditions designated to simulate continuous contact with the ground or with water (use
Class 4 or 5), at time intervals after exposure.
2 Description of the test method
2.1 General considerations
The principal agent for causing emissions from wood exposed to soil is the soil water. The mechanism of
leaching at the wood surface by the soil water is assumed to be identical in nature and severity to leaching
from a wood surface in continuous contact with water.
The mechanism of leaching at the wood surface by fresh water is assumed to
